Maybe , maybe not. I'd probably keep the little house and run plus 50 metres of netting and the energiser. I got some things wrong with the big hen house so IF i ever had hens again I would improve it (I've heard that somewhere before...)
Poor Cocky, having lost quite a few feathers either defending his girls or escaping from the predator, is now moulting so looks a very sorry sight.
I'm going to have a chat with the neighbour who has the field and see whether she's interested in a shared flock - I've decided I want to be free to travel so finding a hen sitter is vital. The cats aren't such a problem - they're semi feral now and they may not even come with me, or perhaps find their way back here. There's one last possible scheme so that I stayed here but OH is away so can't discuss it. I don't think it has much mileage but is probably worth a try.
